Pacific Wolverine Edger Sander

Hand Sanding

- a powerful floorsander designed for the rapid leveling and sanding ofall types of wood flooring excluding thin laminated orveneered floors. Load the sander with abrasivemaking sure that it is skin tight around the drum.Loose sheets will tear. Place the sander on the righthand wall (unless you are making an angled cut onuneven floors) with about two thirds of the floor infront of you. Start the sander with the drum off thefloor then walk forward at an even pace and ease thedrum on to the floor. As you near the end of the pass,gradually raise the drum off the floor. Practice thistechnique before turning on the sander.

Cover the same path you made on the forward cut bypulling the machine backwards and easing the drumto the floor as you begin the backward pass until youreach the original starting point, then ease the drumoff the floor.

When two thirds of the floor is sanded, turn the floorsander around and sand the remaining third in thesame way. Overlap the one third area by 2 to 3 feetwith the two thirds area to blend the two areastogether.

- a powerful edgersander designed for sanding along the edges of afloor without damaging the baseboards or moldings.Also suitable for smaller areas where the Pacific RhinoPFS 8 Drum Sander will not reach like stair treads andclosets. Load the abrasive disc making sure theretaining bolt is tight. Start the edger with the disc offthe floor then lower the disc to the floor as you movethe sander. Work progressively moving the sander ina sweeping motion from side to side.

- to sand difficult to reach areasscrape and sand the floor by hand. Use a scraper toremove old finishes, always scraping in the directionof the grain, and then sand by hand using the samegrit abrasive as you finished with when machinesanding. See Floor Sanding Technique diagrams onpage 5.

WARNING - never bounce the sandingdrum or dwell in one place as this willsand dips and hollows in the floor.

- when the floor is ingood condition - no uneven edges, cupping orcrowning of planks and strips - and you want to re-surface the floor, sanding back to new wood, startsanding in the direction of the planks or strips - withthe wood grain. Start with a grit abrasive.Complete the first cut with the Pacific Rhino PFS 8Drum Sander then sand up to the baseboards anddoor thresholds with the Pacific Wolverine Edger,using a grit abrasive, blending the edges inwith the main floor area. Sweep the floor. Using a

grit abrasive, sand the main floor areawith the drum sander and then complete the floor withthe edger using a grit abrasive. Sweep the floor.Finish sanding the main floor area with the drum floorsander using a grit abrasive.

- when the floor is uneven sand

diagonally at 45 across the room in both directionsusing the Pacific Rhino PFS 8 Drum Sander with acoarse grit abrasive. Only make one cut on bothdiagonals, this will achieve a basic level. Nowcomplete the floor as for a level strip or plank floor.Use the same grit abrasive as was used on the 45 cutfor the first cut parallel to the planks or strips.

- when re-finishing afloor remove as little of the existing surface aspossible. If the floor is badly marked and scratchedand has to be sanded back to new wood use thePacific Rhino PFS 8 Drum Sander and PacificWolverine Edger Sander. Always try a medium gritpaper first, particularly on a diagonal cut. If 90% ofthe old finish is removed and the floor is generallyleveled, you do not need to use a coarse grit abrasive.

The grain of the wood will run in a number ofdirections so sand the floor in the direction of themain source of natural light in the room. If there is nosource of natural light sand in the direction of thelongest side of the room or, if the room is square, inthe direction the furniture is laid out and how peoplenormally use and view the room.

This technique will help mask any imperfections in thefloor. Complete the sanding operation as detailedfor plank or strip floors.

1. Check that power supply is disconnected. Tilt themachine back and rest the handle on the floor.Open the drum guard and remove the abrasivebelt if fitted. Inspect the condition of the drumrubber. A damaged or worn drum rubber mustbe replaced to maintain machine performance.A damaged or worn drum rubber can result inpoor sanding performance with subsequentdamage to the floor surface and can bedangerous in operation.

If the machine moves from side to side whensanding or you are experiencing inconsistentsanding performance this can indicate a worn ordamaged drum rubber. This is caused becausethe drum rubber is not gripping the sanding belt.

2. To replace the drum rubber contact your localService Agent. Pacific Floor Care operate asimple exchange program to replace Rhino PFS8 Sanding Drums. Please contact your localservice agent for information, service levels andpricing.

3. Check the condition of the Abrasive Guides(Ref.142). It is very important that the AbrasiveGuides are maintained in good condition. TheAbrasive Guides ensure that the abrasive beltruns evenly and centred on the sanding drum.Worn Abrasive Guides will cause wear to thedrum rubber, result in poor sandingperformance and cause damage to the machineand floor surface. Worn guides will alsodamage the abrasive belt and may cause it totear.

The Abrasive Guides should not be worn by morethan 1/8” (3mm). The thickness from new is 1/4”(7mm).

4. When fitting new Abrasives Guides or whenreplacing the Drum Guard (Ref. 35) ensure thatthe correct gap is maintained between the edgeof th sanding drum and the Abrasive Guides .

Remove abrasive belt if fitted, using the SpacerGuide Abrasive (Ref.143) adjust the gapbetween the Abrasive Guide and the edge of thesanding drum on both sides of the drum asfollows;

8in wide abrasive - gap 3/32 to 5/32in

200mm wide abrasive - gap 1.5 to 2.5mm

The Spacer Abrasive Guide are of variousthicknesses. User the thicker guides first andadjust the gap using the thinner spacers if

required.

5. Check the condition of the rear wheels (RollersRef.61). The wheels must be free from dirt androtate freely. Check the condition of the ShaftRoller Ref.60, use a straight edge to make surethe shaft is not bent.

1. The motor must be kept free from grease anddust. DO NOT use high pressure air to blow themotor clean. Use a vacuum and soft brush toclean the motor and brush block assembly.

2. The motor brushes must be checked regularly,inspect the brushes every three months or every300 hours from new and then every 100 hours ofuse thereafter.

3. Replace ALL FOUR motor brushes when any onebrush has worn to 1/2” or less in length. BrushesMUST slide freely in the brush holders.
